It is at least the fifth time in less than a month the US companies have made headlines internationally for being hacked. However, previous cases only involved media outlets.

The New York Times, The Washington Post and The Wall Street Journal reported about three weeks ago they had been targeted by Chinese hackers for publishing sensitive stories on the wealth of some of China’s leaders.

Twitter also reported on February 1 that hackers might have accessed the account information of 250,000 users.
